How much life insurance can I put into a TSA?

The rules regarding how much life insurance can be put into a TSA are the same as for any other defined contribution qualified plan. That is, the life insurance benefit must be incidental to the plan. Life insurance is incidental to a plan if no more than 25 percent of your contribution is used for term or universal life insurance or no more than 50 percent of your contribution is used for whole life or variable life insurance.
